Cost Effective Reach

August 23, 2013

I use the great Nikon 70-200mm vrll and this TC-20E III 2x converter gives me a little better reach for some wildlife shots. It performs great, auto focus and all, yes you lose a few stops but using it with the f2.8 you can afford it.
It is an affordable option for 400mm. What I especially like about it is it is easy to carry in your bag and if you need it, use it.
Someday I may be able to justify and afford a large super telephoto, but for now this works just fine.

Only good for f/2.8 lenses

March 7, 2014

I read many, many reviews, most of which warned that the TC-20E III can not shoot tack sharp with the 70-200mm f/4 lens. I did my own test in my home and confirmed the reviews I read. Without the TC the f/4 is every bit as sharp as the f/2.8. With the TC the lens can take good photos, NOT tack sharp. Also, unlike pro-rated Nikon lenses this TC did not feel durable. I took it back for a refund. Best Buy service is great. I would not recommend the TC-20E III for the 70-200mm f/4. I would for the 70-200mm f/2.8.

Great item to extend prime lens!

Bought this to use with a Nikon 300mm 2.8 Lens. AS I shoot mostly birds in the field, thought this to be a great solution to selling the house to buy a prime 600mm lens. Have found that to be the case, you will not be disappointed.

Perfect compliment to Nikon 300mm f2.8

This teleconverter works perfectly as advertised with the above mentioned lens. I maintain full sharpness and only losing 2 stops of light with this lens combo. You will need to research to see if your lens will work with this converter though.
I am thoroughly happy with my purchase.

Gets you reach when needed, but at a cost.

I've used the TC-20E III with a Micro-Nikkor 105mm, 70-200mm f/4, and a 200-500mm f/5.6. The best application was the Micro-Nikkor 105mm because with its f/2.8 aperture it was fast enough to handle the loss of light when using the teleconverter.
It works OK with the 70-200mm f/4 but with the 200-500mm it doesn't autofocus. Of course, you lose some sharpness and contrast when used with slower f/5.6 lens. If I had more long f/2.8 or f/4 lenses, I'd use it more than the limited use I have for it now. In the future I plan on purchasing a Nikon 300mm f/4 PF, I hear that this teleconverter works well with that lens.

Compatible with my Nikon D3200 but not my lens
Posted by: DocWatson from: on The Teleconverter is lightweight and easily attached to my Nikon D3200 camera. However, it would not attach to any of my Nikon lenses. Was very disappointed in that.

Teleconverter was not sharp beyond 30 feet
Posted by: Johnnnn8947 from: Richmond,VA on Using the teleconverter with my 70-200 f2.8 vr2 lens, within 30 feet from the subject, the teleconverter worked great. Beyond 30 feet pictures were not sharp.

Nice to have when you need it
Posted by: Kevin from: Grand Marais, Mn on Bought this for my 400 2.8E and it works great. Focus is still fast and my pictures are still sharp.
